1- Java API to retrieve computer hardware information?

Sometimes you need to use Java to get information of computer hardware, including Serial Number of the mainboard, serial of hard drive, CPU, .

Unfortunately, Java has no such API, or may be there, but it was not released for free for programmers. However, on Windows you can obtain this information by executing the VB script.

2- Get hardware info using vbscript file

 Set objWMIService = GetObject("winmgmts:\\.\root\cimv2") Set colItems = objWMIService.ExecQuery _ ("Select Name,UUID,Vendor,Version from Win32_ComputerSystemProduct") For Each objItem in colItems Wscript.Echo objItem.Name Wscript.Echo objItem.UUID Wscript.Echo objItem.Vendor Wscript.Echo objItem.Version Next

In which Win32_ComputerSystemProduct is a class of Visual Basic, the properties of this class:

Properties
string Caption
string Description
string IdentifyingNumber
string Name
string SKUNumber
string UUID
string Vendor
string Version 
 Set objWMIService = GetObject("winmgmts:\\.\root\cimv2") Set colItems = objWMIService.ExecQuery _ ("Select * from Win32_ComputerSystemProduct") For Each objItem in colItems Wscript.Echo objItem.Caption Wscript.Echo objItem.Description Wscript.Echo objItem.IdentifyingNumber Wscript.Echo objItem.Name Wscript.Echo objItem.SKUNumber Wscript.Echo objItem.UUID Wscript.Echo objItem.Vendor Wscript.Echo objItem.Version Next
Property Value (My Computer)
Caption Computer System Product
Description Computer System Product
IdentifyingNumber 3F027935U
Name Salellite S75B
SKUNumber null
UUID B09366C5-F0C7-E411-98E4-008CFA8C26DF
Vendor TOSHIBA
Version PSPPJU-07U051

3- Use Java to get computer hardware information

OK, above you know how to use vb script to retrieve the computer hardware information. Now you need to use the Java to execute vb script files and get the value returned.

 package org.o7planning.hardwareinfo; public class MyUtility < public static String makeVbScript(String vbClassName, String[] propNames) < StringBuilder sb = new StringBuilder(); for (int i = 0; i < propNames.length; i++) < if (i < propNames.length - 1) < sb.append(propNames[i]).append(","); >else < sb.append(propNames[i]); >> String colNameString = sb.toString(); sb.setLength(0); sb.append("Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")").append("\n"); sb.append("Set colItems = objWMIService.ExecQuery _ ").append("\n"); sb.append("(\"Select ").append(colNameString).append(" from ").append(vbClassName).append("\") ").append("\n"); sb.append("For Each objItem in colItems ").append("\n"); for (String propName : propNames) < sb.append(" Wscript.Echo objItem.").append(propName).append("\n"); >sb.append("Next ").append("\n"); return sb.toString(); > > 
 package org.o7planning.hardwareinfo; import java.io.BufferedReader; import java.io.File; import java.io.FileWriter; import java.io.InputStreamReader; import java.util.HashMap; import java.util.Map; public class GetHardwareInfo < public static void printComputerSystemProductInfo() < String vbClassName = "Win32_ComputerSystemProduct"; String[] propNames = new String[] < "Name", "UUID", "Vendor", "Version" >; String vbScript = MyUtility.makeVbScript(vbClassName, propNames); System.out.println("----------------------------------------"); System.out.println(vbScript); System.out.println("----------------------------------------"); try < // Create temporary file. File file = File.createTempFile("vbsfile", ".vbs"); System.out.println("Create File: " + file.getAbsolutePath()); System.out.println("------"); // Write script content to file. FileWriter fw = new FileWriter(file); fw.write(vbScript); fw.close(); // Execute the file. Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath()); // Create Input stream to read data returned after execute vb script file. BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream())); Mapmap = new HashMap(); String line; int i = 0; while ((line = input.readLine()) != null) < if (i >= propNames.length) < break; >String key = propNames[i]; map.put(key, line); i++; > input.close(); // for (String propName : propNames) < System.out.println(propName + " : " + map.get(propName)); >> catch (Exception e) < e.printStackTrace(); >> public static void main(String[] args) < printComputerSystemProductInfo(); >>
